Abstract

The Eu2+‐doped glass ceramics containing BaF2 nanocrystals were prepared and their luminescence properties were investigated. The excitation spectra of Eu2+‐doped glass ceramics showed an excellent overlap with the main emission region of an ultraviolet light‐emitting diode (UV‐LED) centered at 380 nm. The 450 nm emission of Eu2+ in glass ceramics under the 385 nm excitation was much stronger than that in glass. The Eu2+‐doped glass ceramics containing BaF2 nanocrystals may be used as a potential blue‐emitting phosphor for UV‐LED.
